Abstract

The invention relates to a cutter suction dredger, in particular to a cutter suction dredger positioning mechanism and a positioning method.The cutter suction dredger positioning mechanism comprises an open hole which is formed in a dredger body and is of a cylindrical structure on the whole, a barrel structure is arranged in the open hole, and an annular mounting groove is formed in the inner wall of the lower end of the barrel structure; a guide groove which is communicated with the annular mounting groove and extends upwards in the length direction of the barrel structure is formed above the annular mounting groove, an annular mounting frame is further arranged in the barrel structure and used for mounting a guide pulley, and a supporting block is arranged on the outer circle of the annular mounting frame. The supporting blocks and the guide grooves form sliding guide fit so that the annular installation frame can move to the annular installation groove, and after the supporting blocks rotate by a certain angle, the supporting blocks and the groove walls of the two sides of the annular installation groove form limiting fit. The problems that in the prior art, a barrel structure needs to be overall lifted out to guarantee the maintenance space, and hoisting is difficult due to the fact that the overall weight of the barrel structure is large are solved.

Description

technical field

[0001] The invention relates to a cutter suction dredger, in particular to a positioning mechanism and a positioning method of the cutter suction dredger. Background technique

[0002] With the increasing demand for sea reclamation projects and channel dredging projects, the construction and design of cutter suction dredgers are also developing towards large-scale and intelligent development. Construction plays an extremely important role. The working principle of the cutter suction dredger is to use the rotating reamer to loosen the soil at the bottom of the river or seabed, mix it with water to form mud, suck it into the pump body through the mud suction pipe, and send it to the mud discharge area through the mud discharge pipe.

[0003] In the prior art, the most common application is to use steel pile positioning to realize the dredging positioning function, and realize the lifting and lowering of the main pile and the auxiliary pile, and the switching o...
